Abstract

Science learning requires direct experience in order to develop the ability to explore and understand the natural surroundings scientifically. So far in elementary school at Bukittinggi, the process of learning science only memorizes facts, principles or theories. In science learning, students are not involved in finding or applying their own ideas and they do not instill the values contained in the learning. The science learning process in classroom is not yet fully in accordance with the demands of the curriculum. The teacher provides more material in the textbook without relating it to students' daily problems that are in accordance with the material, thus causing less interesting in learning. The teacher also has not actively involved all students in learning and emphasizes learning only on students who are smarter. The purpose of this study was to increase the activity and learning outcomes of science learning by using a problem-based learning model in SDN 11 Aur Kuning Bukittinggi, West Sumatra. This classroom action research was conducted in 2 cycles with the research subjects of grade IV students with totalling 25 people. The research data were collected through observation and tests. The effectiveness of actions in each cycle from the results of observations and tests is described and then reflected to take corrective action in the next cycle. In science learning, students' learning activities were observed, namely: visual activities, oral activities, writing activities, motoric activities and emotional activities. The research findings show that the problem-based learning model can increase student activity and learning outcomes.

Abstract

EDNRB gene is a gene located on chromosome 13q22, plays a role in the signaling pathway during the development of the ENS intestinal nerves. Mutations in the EDNRB gene in humans are associated with Hirschsprung Disease (HD). Mutations in the EDNRB gene are the second most common cause after the RET gene in cases of HD with a percentage of 5–10%. To detect mutations, PCR products are needed. Primers are one of the basic components of PCR, while optimization of annealing temperature and optimization of primer concentration are factors in the success of primer attachment to the target gene. This study aims to design EDNRB exon 4 gene primers and determine the optimum annealing temperature and primer concentration to amplify the EDNRB gene. Primer design with Geneious Prime, and good primer criteria are analyzed in silico. Optimization of annealing temperature and primer concentration is carried out with gradient PCR and variations in primer concentration. The results of this study obtained the best primers, namely the forward primer 5'- CAGTAAGTGTGGCCTGAAAG-3' and the reverse primer 5'-GTGGAACCGAAGTGACTAGA-3', which amplified the EDNRB gene exon 4. The optimum PCR conditions for amplification of exon 4 of the EDNRB gene were at an annealing temperature of 57.2 ℃ and at a primer concentration of 0.5 μM.

Abstract

The endothelin receptor type B (EDNRB) gene is located on chromosome 13, consisting of 7 exons and 6 introns. The EDNRB protein produced from this gene belongs to the family of G-protein coupled receptors. Mutations in the EDNRB gene play a role in some cases of Hirschsprung's cause, although the frequency is low. This study aims to design primers and test specificity using BLAST primers to determine the specific primer attached to the EDNRB gene. Primers were designed using Geneious Prime, which were then analyzed in silico based on good primer criteria. The results of this research showed that primers made using Geneious Prime produced the best primers, namely forward primer 5'-GAGTTCGGAGCTTTGCCT-3' and reverse 5'-AGCCCACCA TGATTTCA GC-3' and the results of the specificity test showed that the primer specifically attached to chromosome 13 which is the location of the EDNRB gene (13q22) with a product length of 879 bp.

Abstract

Long bean (Vigna sinensis) is a plant from the Leguminosae family, which has an important role in the Indonesian economy because it is widely consumed as food. The purpose of this research is to utilize mutation technology in supporting plant breeding to produce superior long bean varieties. The research method carried out was a non-factorial Randomized Group Design (RAK), namely soaking the seeds of long bean plants with colchicine to see the effect of colchicine treatment on chromosomal mutations in long bean plants. The results showed significant differences between colchicine concentrations of 0.02% and 0.03%. At a concentration of 0.02%, the cell nucleus appeared solid red and in the center of the cell, but the number and shape of chromosomes were not clearly visible. This concentration is not optimal for inducing polyploidy. Meanwhile, at a concentration of 0.03%, the chromosomes were more clearly visible than the previous concentration.

Abstract

Hirschsprung’s Disease (HSCR) is a congenital disorder characterized by the absence of ganglion cells in the intestinal wall, leading to impaired intestinal motility. One of the key genes involved in the pathogenesis of HSCR is the Endothelin Receptor Type B (EDNRB) gene, particularly mutations in exon 6. Detecting these mutations requires specific primers and well-optimized PCR conditions. This study aims to design specific primers for exon 6 of the EDNRB gene using in silico methods and to determine optimal PCR conditions through annealing temperature and primer concentration optimization. Primers were designed based on the EDNRB gene sequence (Accession No. NG_011630.3) using Geneious Prime and validated for specificity using Primer-BLAST. PCR optimization was conducted in vitro using various annealing temperatures 52.8–55.3°C and primer concentrations 0.5–1.1 µM on normal human DNA samples. PCR products were analyzed by 1.5% agarose gel electrophoresis. The primer design for exon 6 of the EDNRB gene yielded the following results: both forward and reverse primers were 20 bp in length, with melting temperatures (Tm) of 58.1°C and 56.1°C, and GC contents of 55% and 50%, respectively. In silico analysis confirmed primer specificity to chromosome 13. Optimal PCR conditions were achieved at an annealing temperature of 55.3°C and a primer concentration of 0.7 µM, yielding a single amplicon of 517 bp.
